"ICANN-enforced domain name transfer policy, effective 11-12-04. It dictates that IF WE RECEIVE A TRANSFER REQUEST (and your domain names are not locked) we must honor the transfer, even if you do not confirm it"

It seems that a new domain transfer policy is being enforced. The above quote is from my Godaddy account. You can read more about the policy here, here and here (all on the ICANN site transfers section).
